Figure REF  illustrates the physical and cyber architecture of two networked microgrids that are used to test the proposed algorithms. For each IBR, its power calculator, voltage controller, current controller, and output filter are modeled according to [1]}. All IBRs have the same parameters. Loads 1, 2, and 3 are modeled by resistors with the values of 25 \(\Omega \) , 20 \(\Omega \) , and 33 \(\Omega \)  for each phase. There is a tie line that can network Microgrid 1 with Microgrid 2. The line parameters are annotated in Figure REF . Each microgrid has its own \(\mu \) AGC which tunes the setpoint of each IBR in the local microgrid.
